Y WASTE VALVE.

Application led September 1 V1925.

The invention relates to valves and `more particularly to pop-up waste valves for use in connection with lava-tories, bath tubs and the like.

Valves of this type have heretofore been provided with a .stem which extended down'- wardly through the center of the outlet pipe or casing. Such a construction tends to retard the outward flow of liquid through `the valve for the reason that the center ofthe outlet pipe where the most rapid flow would occur, and where the liquid would be subjected to the strongest pull, is occupied by the valve stem.

An object of this invent-ion is to provide a valve of the type set forth constructed and arranged to permit a more rapid flow of liquid from the associatedbowl or tub than has heretofore been possible.

A further object of this invention is to provide a waste valve of such construction as to permit a free flow of liquid through the c-enter of the wast-e outlet.

Jalthough architects require a waste valve to be easily removable for cleaning purposes, plumbers object to their being too easily removable, due to the. fact that they are frequently the subject of theft.

A still further object of this invention is to provide a waste valve of the type set forth which is sufficiently difficult to remove to discourage the attempts at theft but which at the same time can be removed for cleaning.

A still further object is to provide a waste valve of the type set forth which is easy and cheap to manufacture, rugged in construction and positive in operation.

These and other objects which will be apparent to those skilled in this particular art are attained by means of this invention7 one embodiment of which is shown for the purpose of illustration in the accompanying drawing, in which Figure 1 is a sectional view of a lavatory having associated therewith a waste valve embodyingl one form of this invention. Fig. 2 is a transverse sectional view on an enlarged scale of the valve shown in Fig. 1 taken on the line 2 2 thereof; and, Fig. 3 is a view in elevation of certain of the valve operating elements shown in Fig. 1.

The particular embodiment of this invention which has been chosen for the purposes of illustration is shown associated with an Serial No. 53,855.

ordinary form of lavatory 5 having the usual waste outlet 6 and overflow outlet 7.

The particular waste valve illustrated includes a hollow plug or casing 8 whose upper flaring en d fits snugly in the waste opening 6 of the lavatory. A suitably formed nut 9 is threaded to the lower end of the plug or valve casing` for clamping the saine in position and a body member 10 serves;

the double function of housing a valve oper ating eccentric and connecting` the casing 8 with the drain 11, all as is well known in this particular art. rl-he casing 8 has the usual openings 12 for permitting the overflow water to flow through the casing at all times.

A hollow plunger which includes in partan open Vframework 13 is slidably mounted within the casing 8 and is provided with a valve head or stopper 14 formed on the upper end thereof and adapted to cooperate with a valve seat 15 formed at the top of the casing 8 and constituting the drain opening of the lavatory. The lower part of the hollow plunger is formed by a tube 16 connected to the lower end -of the open framework 13 by suitable threads 17 so as to conlstitute, in effect, a continuation thereof and the lower end of the tube has an external flange 1t formed thereon.

A valve operating eccentric or cam iinger 19 is positioned within the housing 1() at one side't-hereof and has a stein 2O eX- tending through a packing oint in the rear wall of the housing. An operating rod 2,1 connects the eccentric stem with the usual operating mechanism 22. The operating rod 21 is preferably hexagonal in cross section so as to provide a larger number of adjustments between the operating mechanism .f

and the eccentric than is obtainable with the square rods hitherto in use. The eccentric linger is positioned at one side of the housing 10 and engages the lower rim and flange of the plunger formed by the hollow extension tube 16.

Such a construction provides a completely unobstructed waste outlet wherein the Huid can flow through the center of the valve casing where it will be subjected to the strongest pull with the result that the exit of the liquid through the valve will be materially accelerated.

In order to render the valve sufficiently difficult to remove in order to prevent the easy theft thereof, while at the same time permitting its removal for the purposes of cleaning, the casing is preferably provided with a lug 23 extending inwardly thereof. ir circumferential flange Qel is formed on the valve. plug 13 about centrally thereof and a slot 25 is formed in the flange to permit it to be moved upwardly past the lug' A similar flange 26 is provided at the bottom of the valve plug 13 and a slot 27 is formed thereon but is preferably odset from the slot '25 in the upper flange.

ln order to remove the valve it is necessary to twist the same until the slot 25 coincides with the lug 23. The valve can then be lifted until the lug contact-s with the lower flange 26 when it must again be turned until the lug is able to pass through the slot 2?. llthe valve can then be lifted until the lug contacts with the flange i8. While no yslot is provided in the flange i8 the latter can be moved out of the casing by tilting the valve.

N hat l claim as new and desire to secure by Letters Patent is:

l. A, waste valve having in combination, a casing forming a waste outlet, a hollow plunger slidable in said casing and provided with a plurality of circumferential Vflanges havin@` offset slots therein a lue' ,in

e, t: 7 o

said casing adapted to engage said lianges, a stopper formed on said plunger for opening and closing the end of said casing and means for'voperating said stopper.

2. A waste valve having in combination, a casing forming a waste outlet, an open framework slidable in said casing, a stopper formed on said framework for opening and closing one end of said casing, circumferential slotted flanges on said framework with their slots in oset relation, a lug in said.

casing adapted to engage said flanges, an extension tube secured to the bottom of said framework and provided with a circumferential flange adjacent the bottom thereof and an eccentric at one side of said casing and engaging said tube for raising and lowering said stopper.

3. In combination in a waste valve, a ported casing flanged at its upper end and provided with a stopper seat, a ported 'hollow member slidably mounted within said :asing and having an enlarged head at its upper end forming a stopper for cooperation with said seat, a tubular member threaded to said ported member and provided with an outwardly extending circumferential flange, a lug extending inwardly from said casing for Contact with said 'lange to prevent withdrawal of said ported member from said casing except when tilted and means for raising said stopper.

el. ln combination in a waste valve, a casing forming a waste outlet, having a flange at its upper end and provided with a stopper seat, a hollow plunger slidable in said casing, having a stopper for cooperation with said seat and a plurality of circumferential ianges having offset slots therein, a lug in said easing for engaging said fianges and means for raising said plunger.

5. lu combination in a waste valve, a ported casing forming a waste outlet and having a stopper seat formed at its upper end, a stopper for cooperation with said seat and having a hollow ported stein slidable in said casing and provided with circumferential flanges having offset slots, a lug projecting inwardly from said casing beyond the periphery of said flanges, a

flanged sleeve threaded to said sto )er stem a rotatable member arranged to contact with the lower part of said sleeve for raising said stopper and adjustable means for operating said rotatable member.

ln testimony whereof, I have hereunto subscribed my name this 25th day of August, i925.
